ERROR: Failed to resolve: com.android.support.test.espresso:espresso-core:2.2.2

Android studio跑别人的项目，经常会出现这种不匹配的情况。
解决方法：
1.

2.添加

maven {
    url "https://maven.google.com"
}

 

结果：

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}
